Primary (Invictus) Configuration

BV (2.0) 1,245[2][3]


The Grigori is one of the Word of Blake's new Celestial series OmniMechs designed by Doctor Devon Cortland. The Grigori (named after fallen angels from Christianity) was added to the Word of Blake Militia's arsenal in late 3069 as Doctor Cortland oversaw the final production personally. It is constructed on a standard chassis, but makes use of eleven tons of Light Ferro-Fibrous armor, a light fusion engine, and an XL Gyro; as well as the small cockpit that is common to all of the Celestials. Like the other Celestials, the Grigori has a C3i Computer to help direct its fire.[2]

Weapons and Equipment[edit]

Unlike the rest of the Invictus variants of the Celestials, the Grigori's most common version is a missile-heavy 'Mech, armed with an MRM-20, LRM-15, and a Streak SRM-4. If it runs out of ammunition, the Grigori has a Light PPC and a Retractable Blade for close quarters combat. Despite the 'Mech's youth, it is already infamous for concentrating its four tons of ammunition in the right side of its torso, even though the location is protected by CASE.[2]

Alternate Configurations[edit]

  • Alternate Configuration B (Infernus
    Another missile-heavy variant, the Grigori B mounts an Artemis IV-guided MML 7 in each arm. A plasma rifle provides respectable firepower and forces conventional units to reconsider attacking the Infernus variant. A Medium Pulse Laser provides a more accurate weapon. A rear-mounted ER Small Laser makes small units think twice about attacking the 'Mech's rear. Like the Invictus, this configuration can also jump up to 120 meters. BV (2.0) = 1,408[4][6]
  • Alternate Configuration C (Comminus
    This variant also jumps, though it also adds a Guardian ECM Suite for further defensive measures. Three MRM 10s aim to take advantage of the integral C3 network, while twin Streak SRM-6s spreads fire out all over an enemy target. Two ER Medium Lasers back up the missile weapons in case they run out of ammunition. BV (2.0) = 1,438[4][7]
  • Alternate Configuration D (Luminos
    Six Improved Jump Jets vault the Grigori D up to 180 meters. A Heavy and a Light PPC allow it to snipe effectively. Two ER Mediums and a pair of ER Smalls back up the PPCs in case an enemy gets under their minimum range. BV (2.0) = 1,568[4][8]
  • Alternate Configuration E (Eminus
    The Eminus configuration carries an experimental Thunderbolt 15 and two tons of ammunition. An ER PPC supplements its fire at range. If an enemy gets closer, the Grigori E can do more damage with five ER Medium Lasers and an ER Small. BV (2.0) = 1,544[4][9]
  • Alternate Configuration U (Exanimus
    The Exanimus configuration is designed to defend underwater locations. Equipped with a quartet of UMUs, it can travel at approximately 46 km/h underwater. The use of a MASS allows support forces to rescue the pilot in case of a hull breach. Unlike most designs intended for underwater combat, the armament of the Exanimus lacks torpedoes. Instead it carries a Heavy PPC, ER PPC, a pair of ER Medium Lasers and a pair of ER Small Lasers. To ensure it finds enemy forces early, it also carries a Beagle Active Probe. BV (2.0) = 1,604[10]

Custom Configurations[edit]

  • Grigori Rufus 
    Based on the Infernus, the custom configuration of Opacus Venatori member Rufus Black Bear retains the paired Artemis enhanced Independence 9SL MML 7s and rear facing Diverse Optics ER Small Laser but swaps the plasma rifle and medium pulse laser for a Kinslaughter-4 Light PPC with a C4 PPC Capacitor and a Ramtech 5500V Medium Variable Speed Pulse Laser, replacing the Plasma ammo with an extra ton of missile reloads. BV (2.0) = 1,399 [13]
